BUILDINGHTILE.

To all whom t may concern:

Be it known that l, AVILA O. THOMAS,` a citizen of thel United States, residing at Detroit, in the county of Wayne and State 0f Michigan, have invented a new and useful Building-Tile, of which the' following is a specification.

This invention relates to wall constructions and its object .is to provide a Wall comprised of two-part hollow blocks connected by tie members in a novel and eilicient man'- ner, and arranged at suitableintervals/to receive a concrete lling reinforced by said tie members and forming columns for strengthening the wall and supporting roofsfloors, beams, or other loads. f L

Other objects are to Vprovide a hollowblock wall that may be rapidly erected, and

one that will have abutting faces-of considl erable area between adjacent tiers of blocks so as to allow a large spread of mortar.

The provision of a'tWo-part block comprised of duplicate members that may be` easily moldedis another feature.

r1`hese objects are accomplishedv bythe construction disclosed in the accompanying drawings, wherein: 4

Figure 1 is a perspective view of one of the members which when arranged. in pairs form hollow blocks.

Fig. 2 is an end View of th'e same, showing also a portion of a similar superimposed member.

Fig. 3 is a top view of the same.

Fig. 4 is a horizontal section through aV main wall and a partition Wall embodying the 'novel features herein disclosed.

Fig. 5 is a fragmenta'r perspective view of a columnar portlon o the wall showing. diagonal tie and anchor members for secureing the tiles together. A

lx1-these views the reference character 1 designates a tile, either baked or air-dried, which comprises a Hat, rectangular plate having ribs 2 and 3 projecting from one'of its faces, the ribs 2 being set back from the respective ends of the tile and the ribs 3 extended between the ribs 2,. respectively, along the top and bottom edges of the tile. 'lhe ribs 2 have edge faces in a common plane parallel to the plate 1, and the ribs 3 have edge faces which intermediate the tile extremities have small areas 3. inthe plane oi" said edge faces of the ribs 2. At each side of the areas 3. the ribs 3 are gradually reduced in height, being almost flush with Specification of Letters Patent.

Application led March 12, 1917. Serial No. 154,106. j

-When two of said tiles are arranged' with the plates ll'parallel and the ribs 2 and 3 abutting, they form a hollow block. When a wall is formed of tiers of said blocks, with the transverse vertical oints of the tiers registermg, columnar openings 5 will be formed at said joints between the ribs 2 of adjacent blocks and the end portions of the plates 1. i

Such a wall may be regarded as comprised ,of two parallel partitions each similarly formed by .tiers of tiles. To maintain these partitions 1n parallel relation, and.' to prevent relativemovement of` the blocks or of the tiles forming the blocks, tie members 6 ribs 2 with-the plates 1, and have their extremities oppositely bent as indicated at 7 to afford a better anchorage. By filling the spacesj with concrete or similar cementif tious material embedding the tie members 6, celu-mns 5 are formed which strongly reinforce the wall and serve to carry the weight of floors, roofs, beams,- or any other'load. It will not ordinarilyibe necessary to form these columns i'n" all of the spaces 5, but only at the points whereconsiderable loads ale concentrated.

The main advantage 4"derived from the Vuse of two-part hollow blocks, suchas have been above described, lies in the fact that any use of cores is eliminated during the molding of the blocks, so that the manufacture is simplified and cheapened. The provision for producing concrete columns within the wall itself wherever `desired is highly advantageous in that it eliminates they setting up and taking down of a form for pouring -the column and avoids any interruptions in the continuityof the wall surfaces by the columns. A high degree of rigidity is imparted to the wall by the embedi ding in the columns of the tie members 6.' since by thus prohibiting any relative movement of said members, there is also positively prevented any relative motion of the tiles connected' by said members. The ribs 3, since they are Hush with the top and bottom edges of the tiles, give stability to the wall by furnishing each tile with surfaces of considerable area'to respectively support said tile on the underlying tile and to form a seat for the overlying tile.

By the term tile as used in the foregoing specification and following claim is understood any cementitious member whether baked' or Water-set.

What I claim is:

In 'a wall construction, the combination with tiers' of blocks vhaving registering 15 transverse vertical jointsand forming'a co1- umnar opening at said joints, each of said blocks comprising two tiles having abutting portions forming walls of said openings, two sets of tie members extending diagonally the connected tiles and projecting therefrom 2 diagonally of the columnar opening.

In testimony whereof I sign this specification.
